Specification of Letters Patent.

Patented Feb. 23, 1909.

To all whom it may concern:

Be it known that I, FREDERICK W. Ooornn, a citizen of the United States,residing at Charleroi, in the county of Washington and State ofPennsylvania, have invented certain new and useful Improvements inChurns; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to churns and pertains more particularly to thedasher blades thereof.

It is an object of the invention to provide a novel device of thischaracter wherein the dasher blades may be properly held by the dashershaft.

It is also an object of the invention to provide a novel device of thischaracter which will be simple in construction, efficient andadvantageous in practice and comparatively inexpensive to manufacture.

\Vith the above and other objects in view the invention consists in thedetails of construction and in the novel arrangement and combination ofparts to be hereinafter more particularly referred to.

In describing the invention in detail reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters of reference denote corresponding parts in the several views,and in which,

Figure 1 is a view partly in section and partly in elevation of a churnand its operating mechanism, illustrating the invention a plied. Fig. 2is an enlarged sectional view, il ustrating the invention in detail,and, Fig. 3 is a view in perspective of the invention detached and inassembled relation.

In the drawings 1 denotes the base from which is erected the upright 2.Resting upon the base 1 is the churn body 3. J ournaled in the upright 2is the shaft 4 which has affixed thereto the operating handle 5 and agear wheel 6. The upper portion of the upright 2 is carried forward, asat 8 and is rovided with the depending portion 9.

Iounted in the depending portion 9 and the upright 2 is the countershaft10 which projects beyond the upright and has secured to said projectingportion the balance Wheel 11. Said counter shaft is provided with a gearwheel 12 which meshes with the gear wheel 6. The shaft 10 is furtherprovided with the bevel gear 13. Extending vertically through aperforation in the top section 8 and held in position therein by a setscrew 14 is a pin 15. This pin 15 extends within a recess 16 in theupper end of the dasher shaft 17 and said dasher shaft has fixed uponits upper end the bevel gear wheel 18 which meshes with the bevel gearwheel 13 before referred to. The shaft 17 also passes through clips 19pivotally held by the lower end of the depending portion 9. The lowerend of the shaft 17 rests in the bearing 20 attached to the bottom ofthe churn body 3. IVithin the churn body 3 there is provided a pluralityof vertical breakers 21 and said churn body is further provided with acover 22. The dasher is attached to the shaft 17 adjacent the lower endthereof and consists, preferably, of two sets of wooden bladespositioned one above the other having their faces arranged on a properbevel. It has been found best that each set consist of two blades 23arranged at right angles to and mortised into each other, and each setis separated a desired distance one from the other by the interposedblock or spool 24.

The overlapping portions of the blades 23 are provided with openings 25which are adapted to register with an opening 26 in the spool 24.Through these openings 25 and 26 is threaded a metallic sleeve 27 whichloosely embraces the shaft 17. It will thus be seen that the sleeve 27efficiently locks the various parts of the dasher and in assembling thedevice it has been. found best that the openings 25 and 26 be of lessdiameter than the diameter of the sleeve 27, as is thought to beobvious.

In order that the dasher may be held against movement 011 the shaft 17 acollar 28 snugly embraces said shaft and said collar has threadedtherethrough a set screw 29 adapted to bind against the shaft 17 andhold the collar 28 against movement thereon. This collar 28 is providedwith an exteriorly threaded boss 30 which is adapted to engage aninteriorly threaded end portion of the sleeve 27.

While there has been shown but two sets of blades it is to be understoodthat as many may be employed as desired, although it has been found inpractice that two sets perform their functions with great facility. Ithas also been found desirable that these blades be formed of Wood as thebutter Will not stick to Wood, thus overcoming a great objection tometal dashers.

I claim:

A dasher of the class described, com rising a shaft, pairs of blademembers app ied to said shaft, the blades of each pair extending atright angles to each other and mortised together and having openingsthrough their mortised portions, blOGkS interposed between each pair ofblades and having openings co-incident With the openings in said blades,an exteriorly threaded sleeve adapted to be secured through saidopenings to said blocks and blades, a collar having a threaded 15surface at one end engaging a corresponding surface at one end of saidsleeve and means for locking said collar upon said shaft.

In testimony whereof I have signed my name to this specification in thepresence of 20 tWo subscribing.Witnesses.

FREDERICK W. CGOPER.
